Lowest temperature in Chicago on Sep 22, 2026?

Kalshi

All markets resolve based on the minimum temperature recorded at Chicago's CLIMDW station on September 22, 2026, as reported by The Weather Company. Each market corresponds to a specific temperature range: below 50°F, 50-51°F, 52-53°F, 54-55°F, 56-57°F, or above 57°F. The Weather Company's official report is the sole source for resolution, even if other weather services show different values. Preliminary data may be subject to rounding or conversion differences, and users should exercise caution when interpreting early readings. If the Exchange identifies a material error in the initial non-preliminary data, it may delay expiration until a corrected version is published or until the expiration date, whichever comes first. If no valid data remains available by the expiration date, all markets resolve to the last fair price determined by Kalshi. The 'Final' status on weather.com/kalshi is informational only and does not guarantee data accuracy or exempt markets from potential revisions under these rules.
